Comment 31 for bug 561210

Applying the patch referenced in the previous comment, the situation with regards to NFS deadlocking is improved -- the local terminal no-longer locks up -- but there are continued issues with processes blocking in 'D' (disk-wait) when they should not.

(For example, automounted NFS volumes not involved in a transfer-in-progress which try to automatically unmount after a period of inactivity will have their 'umount' processes block in disk-wait until the transfer has completed.)
